CHAPTER I


INTRODUCTION

Studies of sensory deprivation have been a fruitful method of studying a S's response to the relative absence of the usual environmental stimuli. One of the significant findings is the relatively high percentage of normal Ss who experience various hallucinations when placed in isolation. This hallucinatory activity has been studied largely in terms of the experimental conditions most likely to elicit this aberrant behavior. The personality factors of the Ss responding with hallucinatory activity has been less thoroughly studied.

Although many studies have utilized personality measures, there does not emerge any consistent, significant relationship which would predict the tendency to respond with hallucinations. The Zuckerman, Albright, Marks, and Miller study (1961) concluded, "Personality correlations with response to isolation were few and no strong support was obtained for the hypothesis concerning these relations" (p. 16). They suggested further research using normal Ss who were at the extremes of some personality measure.

An important personality measure which has not been systematically studied in sensory deprivation is anxiety.

Anxiety plays a central role in human behavior. Hallucinatory activity could well be an expression of anxiety. Fenichel (1945) points out that the anxiety hysteric frequently experiences hallucinations, in addition to other anxiety reducing symptoms.

Sensory Deprivation and Perception

Hochberg, Triebel, and Seaman (1951) reported unusual behavior in 11 Ss while attempting to explore the parameters of color adaptation. A similar observation was made by Cohen (1960) who reported his Ss suffered from perceptual disturbances, dizziness, and depersonalization.

Heron, Doane, and Scott (1956) had three Ss in sensory deprivation for six days, and then tested them for perceptual disturbances. They found evidence of gross disturbances. Freedman and Greenblatt (1960a) subjected 30 Ss to an eight-hour period of sensory deprivation, and then

administered these Ss some standard perceptual tests. They, however were unable to find any significant distortions. Doane, Mahatoo, Heron, and Scott (1959) using up to four days in isolation found that visual perceptions were more grossly disturbed in 13 Ss restricted to a cubicle, than were found in four Ss who were ambulatory. This was further supported by Courtney, Davis, and Solomon (1961) who varied the amount of movement that their 18 Ss could experience while undergoing four hours of sensory deprivation.

The problem of perceptual disturbance resulting from







sensory deprivation has not been completely settled. The amount of time spent in isolation and the amount of physical restriction appear to be relevant variables. However, both of these variables could be associated with intensifying the S's anxiety. Profound anxiety could well interfere with performance. The function of anxiety was further suggested by the fact that the perceptual disturbances quickly abate, leaving no known permanent effects.

Sensory Deprivation and Personality

Specific research on the relation of personality to response elicited in sensory deprivation have not yet yielded conclusive results. Azima and Cramer (1956) and Azima and Cramer-Azima (1957) have done several sensory deprivation studies with a total of 19 mentally disturbed Ss. They found that the obsessive-compulsive neurotics became psychotic under such conditions. Azima and Cramer reported the following pattern that their Ss seemed to follow during sensory deprivation: frustration leading to aggressions followed by an introversion of the aggression causing a split in the ego, and finally depersonalization.

Goldberger and Holt (1958, 1961) and Holt and Goldberger (1959) have studied the response to sensory deprivation with selected personality correlates in 30 Ss. They found that the Barron Ego Strength Scale (Es) from the Minnesota Multiphasic Personality Inventory (MMPI) correlated .71 with the adaptive reactions to sensory deprivation. There were also findings in relation to







passivity and adaptation. Male Ss who scored high on feminine identification were able to adapt; whereas, male actors (some with a homosexual orientation) with low ego strength were nonadaptive.

Wexler, Mendelson, Leiderman, and Solomon (1958) using a tank type respirator for a 36-hour period with 17 Ss, found one significant personality variable related sensory deprivation. This was the Need Exhibition scale from the Edwards Personal Preference Schedule. This was negatively correlated with the length of time the Ss remained in sensory deprivation.

Bresslers, Silverman, Cohen, and Shmavonian (1959)
created an artificial traumatic neurosis in their study of sensory deprivation. They simply abducted three student .s, placing each S in sensory deprivation for two hours with no instructions. They found that this was extremely upsetting to these Ss, even to the point of precipitating

some rather serious emotional upsets.

Smith and Lewty (1959) found that nine female Ss
could endure sensory deprivation for significantly longer periods than could-the 11 males in their study. They further reported that the calm, placid person of average or slightly below average intelligence was the best S. They reported a behavioral sequence: (1) sleep, with those Ss who did sleep being better able to tolerate the conditions;
(2) a period of restlessness and agitation; (3) the development of disorders in thinking; and (4) the last stage, panic. Isolation was then terminated.







Freedman and Greenblatt (1960b) studied 30 Ss using an eight-hour period of sensory deprivation under three conditions: nonpatterned vision and auditory input, blacked out vision and auditory input, and social isolation. They found that the Ss who normally experience hypnagogic imagery and tended to have a rich visual experience were more apt to report hallucinations.

Cambareri (1959) investigated the effects of sensory deprivation through water immersion with the suggestible and nonsuggestible. Using 20 graduate students in psychology as Ss, he found that the suggestible Ss were able to tolerate isolation longer. The suggestible Ss were also able to produce more regressive phenomona, were less threatened by it, and were less defensive about the experimental situation.

Grunebaum, Freedman, and Greenblatt (1960) investigated some gross clinical types. They reported that the three schizoid Ss found the experience undisturbing, experienced little imagery, and in general showed a lack of involvement in the whole proceedings. Two borderline state Ss reacted differently. The first S, who admitted to enjoying both homosexual and heterosexual practices, became panic stricken when faced with his own imagery, while the other S, who was heterosexual, passive, and withdrawn, was able to tolerate very threatening fantasies and imagery. Two psychopathic Ss forced the experimenter to terminate the experiment by taking off the equipment, telling the





6


experimenter that they did not think it made any difference. The conclusion of this study was that the Ss react in their characteristic manner in an ambiguous situation.
Davis, McCourt, and Solomon (1960), studying the effects of visual stimulation on hallucinations during sensory deprivation, kept ten Ss in a tank type respirator for ten and one-half hours. The found a significant relationship between the Ss who tended to respond with visual hallucinations and their performance of a "hidden figures test." They found that the better the performance, the more likely the S would experience visual hallucinations.
Although a summary of personality and sensory deprivation was complicated in view of the diverse techniques and the various Ss used, anxiety appeared to play a strong role in many studies. The Ss found to experience difficulty in sensory deprivation were: the obsessive-compulsive neurotics, Ss needing to be the center of attention, those with low ego strength, the nonsuggestible, and certain borderline states. On the other hand, there did appear to be less anxiety in those Ss who were able to adapt or endure isolation for longer periods: the Ss with high ego strength, those who were passive and calm, and the
suggestible.
The percentage of Ss reporting visual hallucinations in sensory deprivation had not received a systematic analysis. It was difficult to ascertain the proportion of So who made such a response because of the diversity of approaches





7


to sensory deprivation, the temporal differences, and inadequate information on this point. The percentage of Ss responding with visual hallucinations varied between

5 per cent (Smith and Lewty, 1959) and 100 per cent (Lilly, 1956; Shurley, 1960). Taking an average of five studies in which the Ss were submitted to unaptterned vision for periods of four to eight hours, approximately 37 per cent of these Ss experienced visual hallucinations.

Although visual hallucinations were reported by a high percentage of Ss, only three studies reported significant variables that would identify these Ss. These studies indicated that good performance on the Embedded Figures est (EFT), the more suggestible Ss, and those who have visual hallucinations in sensory deprivation. This group also appeared to have a high level of anxiety. It seemed that visual hallucinations and anxiety were related. If this was so, then one could expect a group of Ss chosen for having a high level of anxiety to respond to sensory deprivation with visual hallucinations.

Hypotheses

On the basis of the foregoing review of the studies on sensory deprivation and personality, it was felt that the role of anxiety was sufficiently important to warrant the following hypothesis:

Hypothesis 1.--That hallucinoidal visual imagery

will be elicited from the more anxious Ss, and not from the less anxious Ss.





8


In order to explore further the area of personality relationships, and specify them more completely as they have been studied under sensory deprivation, major measures of the IPAT 16 P.F. Test and the clinical scales of the MMPI will be obtained on the Ss. The following hypothesis is presented:

Hypothesis 2.--That Ss who have hallucinoidal visual imagery will not show differences on these personality measures.

The Goldberger and Holt studies (1958, 1959, and

1961) have indicated that there was a positive relationship for ego strength and the S's ability to adapt to sensory deprivation. They obtained a rho correlation of 0.44 between the MMPI Ea scores and visual imagery. An attempt will be made to expand these findings. The IPAT ego strength factor will be used in addition to the PMMPI Es. The following hypothesis is offered:
Hypothesis 3.--That Ss with higher ego strength scores will have more hallucinoidal visual imagery than will the Ss with lower measures of ego strength.

The Freedman and Greenblatt study (1960b) reported that Ss who had experienced hypnogogic imagery and had rich visual experiences had a higher incidence of visual hallucinations in sensory deprivation. In the light of these findings a 20-item questionnaire was constructed. The purpose of this Index of Hallucinatory Activity (IHA) questionnaire (Appendix II) was to obtain a hallucinatory





9

behavior differential on the Ss. The following hypothesis is to be tested:

~Eiothi 4.--That those Ss with higher scores on the Index of Hallucinatory Activity questionnaire will respond with more hallueinoidal visual imagery than will the Ss with lower scores.

Visual hallucinations were positively correlated with the performance on a "hidden figures test in the Davis, MeCourt, and Solomon study (1960). These findings will be further investigated. The following hypothesis is offered:

Hypothesis 5.--That an analytical visual perception, as measured by an embedded figures test, will show a positive relationship with the production of hallucinoidal visual imagery.












CHAPTER II


METHOD

The present study utilized a brief sensory deprivation procedure, similar to the experimental procedure of Hochberg, Triebel, and Seaman (1951), to seek differences in those Ss who responded to chromatic, homogeneous visual stimulation (Ganzfeld) with the response of hallucinoidal visual imagery. Anxiety was the main personality difference in the two groups of Ss. A ten-minute exposure to the chromatic Ganzfeld constituted the sensory deprivation condition.

The main personality measure under study was the sensitizer-represser dimension. Welsh (1956) developed M~PI scales for identifying these two groups, the A scale for sensitizers and the R scale for repressers. The sensitizers had a high loading on the MMPI scales of Psychasthenia and Schizophrenia, and low scores on the K scale. They tended to be dysthymic (tending towards depression) and dysphoric (generalized anxiety, restlessness, and depression of spirits). Welsh described this factor as anxiety or being generally emotionally upset. On the other hand, the repressers were described as those Ss who characteristically rely on the defense mechanism of repression and denial. They showed a 10







moderate loading on the M PI scales of Hypochondriasis, Depression, and Hysteria; while they showed a moderately negative loading on the Hypomania scale. Welsh reported that the main factor here was a reliance on the defense mechanism of repression.

The research of Holzman and Klein (1956) with what they called sharpening and leveling and the research of Witkin, Lewis, Machover, Meissner, and Wapner (1954) on the field analytical and the field dependent characteristics suggested a similarity to the sensitizer-represser work of Welsh. The sensitizers had much in common with the sharpeners and the field analytical: alert to changes in the environment, resistant to "ground" influences, and more active. The repressers had some of the traits of the levelers and the field-dependent: passive, dependent, exaggerated need for nurture and succor.

The use of the term visual imagery in the several
studies indicated some confusion. Most researchers preferred to use the term hallucination. Some, like Holt, preferred the term imagery or visual imagery, possibly feeling that the term hallucination should be reserved for the more disordered mental conditions. In the present study, the term hallucinoidal visual imagery was used to label the visual sensations perceived by the Ss in response to the chromatic Ganzfeld.

Subjects
The Ss utilized in this study of sensory deprivation





12

were 56 female student nurses in psychiatric training at the Milledgeville State Hospital, Milledgeville, Georgia. Their ages ranged from 19 to 20 years. They were at the end of their second year, or the beginning of the third year of their training, in a three-year nursing school program. Their home hospitals were located in the state of Georgia. The Ss were selected each quarter during a one-year period from a total of 299 students. They were selected on the basis on their scores on the A scale and the R scale of the MMPI. Welsh (1956) developed the scales for making this selection, and his female sample was used in determining the cutoff scores for the Ss utilized in this study. Ss were selected whose scores were in the fourth quartile of one measure, while also being in the first quartile on the other measure. There were 28 sensitizers and 28 repressers.

The Ss were encouraged to participate in the study
by the promise of a brief personality evaluation based on the test battery administered to them. It was noted that the Ss were highly motivated, as no one failed to appear after being selected, no one missed an appointment, and no one was even late for an appointment. Apparently, the Ss were able to keep the nature of the study secret until a group had completed the sensory deprivation procedure, as only two Ss admitted to any real foreknowledge of the experimental procedure.





13

App.aratus

Thehe S were asked to lie on a cot qwith eye cups placed over each eye. The eye cups were made from halved ping pong balls and -ere held in place by means of a strip of clear, plastic wrapping material. A red light before a 10-inch aluminum parabolic reflector provided illumination measured at approximately 54-foot candles by a Macbeth illuminometer. The source was placed approximately 12 inches immediately above the face of the supine S. The source was placed in position only after the S had the eye cups in place, Figure 1 is a posed photograph of the experimental room and apparatus.

The room used for the study was located in a dormitory building. It was windowless, quiet, and completely darkened during the experimental procedure. A tape recorder, placed within three feet of the head of the S, recorded verbalizations of the S while she was participating in the experiment.

Procedure

The Ss where chosen for the study within two weeks after their arrival at the Milledgeville State Hospital. They were administered the MMPI. In order to maintain a degree of anonymity, each MMPI answer sheet was assigned a number to which the student nurse was asked to add her mother's -maiden name. Within the next week, the Ss were selected for the study and were administered the remainder of the test battery. This included the following: the








IPAT 16 P.F. Questionnaire, 1956 edition, form A; the Index of Hallucinatory Activity (IIHA) questionnaire (Appendix II); and Maslow's Security-Insecurity Inventory (S-I). The Witkin (1950) Embedded Figures Test (EFT), short form (Jackson, 1956), was administered after the sensory deprivation.
Specific variables from the MiPI and the IPAT were investigated. The scales from the IMPI were: K, hypochondriasis (Hs), depression (D), hysteria (m), psychopathic deviate (Pd), masculinity-feminity interest (Mf), paranoia (Pa), psychasthenia (Pt), schizophrenia (Sc), hypomania (Ma), Barron's (1953) Ego Strength (Es), and Taylor's (1953) Manifest Anxiety (iAS). The factors utilized from the IPAT were the standard 16 factors plus the second order anxiety factor and the second order introversion-extrovers ion factor.

The scoring of the tests was standard with the

following exceptions. The raw scores on the IPAT were converted to the norms of the general population, nonstudent, women, 1959 for the calculation of the second order factors. The IA was scored by totaling the number of times the S answered a statement "Often" or "Sometimes."

When the S was lying on the cot with the eye cups in
place, the instructions were read, the red light turned on, and the overhead illumination was turned off. Except for the red light, the room was then completely dark. Instructions read to the Ss were as follows:
















































of







This is a study in color adaptation. I want you to
report any change in color, any unusual feelings, or anything you might see,. I would like a constant report from you which will be tape recorded. I will ask
you questions from time to time. Please lie as still as you can. Don't move about any more than you must.
Now, what do you see?
It was found necessary to ask the Ss for a report at oneminute intervals, as there was a strong tendency for the Ss to remain silent. The questions asked were: "What color is it," "What do you see nowj" or "How do you feel now." Only one question was asked at each interval.; and# in general, the expert enter limited his verbalizations

The instructions used were a deliberate attempt to disguise the real purpose of the study. Kandel, Myers, and Murphy (1958) have indicated that prior instructions tend to structure the Ss response.

The frequency with which the questions were asked

during the sensory deprivation procedure might limit the interpretation of the results. There were two factors involved, one positive and one negative. On the positive side was the necessity of ganing an ongoing verbal report. Visual or other sensory experiences might well be minimized or distorted in a post-experimental interview. On the negative side was the fact that the experimenter's voice tended to act as a reality guide. This was anticipated, and later substantiated in the case of S 270 R 24.
Immediately after the ten-minute interval of sensory deprivation, the S was interviewed as to how she felt and what she had experienced. The standardized interview





17

(Appendix III) was a modification of the Goldberger and Holt (1961) post-experimental interview. A rating scale (Appendix IV) was utilized to evaluate the S's behavior.
The verbalizations elicited from the Ss while undergoing sensory deprivation were rated by six judges for evidence of hallucinoidal visual imagery. The judges referred to the Type of Hallucination rating scale (Appendix IV) in making their judgments. This rating scale was a modification of the scale reported by Vernon, McGill and Schiffman (1958). Four of the six Judges had to agree in their independent rating on the presence of verbalizations which indicated the probability of S experiencing hallucinoidal visual imagery. The resulting unreliability of the five categories of the types of hallucination indicated that the most feasible method of evaluation would be a two-fold classification: those Ss who experienced hallueinoidal visual imagery and those Ss who did not have this experience.

An appropriate method for analysing the data obtained was to compare the mean scores on the various personality measures for the group who experienced hallucinoidal visual imagery and the group that did not have this experience. The t test for the difference between independent means was used to test the null hypothesis.
A chi square was used to determine the relationship in the frequency distribution of the hallucinoidal behavior by the sensitizers and the repressers. A two-by-





18

two chi square wss utilized to test the distribution of the sensitizers and the repressers who had and had not experienced hallucinoidal visual imagery.

Seven rating scales and the post-experimental interview were searched for significant relationships.













CHAPTER III


RESULTS

Hallucinoidal visual imagery was elicited from 22 (395) of the Ss during a ten-minute period of color adaptation in a field of homogeneous visual stimulation (Ganzfeld). The presence of hallucinoidal visual imagery was established through the rating of the verbalizations of the Ss during the experimental procedure. Six judges were used for the evaluation, and agreement among four of tudges washe six judges was the criterion for the presence of hallucinoidal visual imagery. The Ss judged by this criterion are presented in Appendix I (Table 2). The transcription of the verbalizations of the Ss are presented in Appendix V.

It was noted in placing the Ss in the hallucinoidal
visual imagery group that the Type of Hallucination rating scale (Appendix IV) was not sensitive enough to establish a quantification of the type of imagery. Therefore, the analysis of the dependent variable was limited to a dichotomy: those Ss who experienced hallucinoidal visual imagery and those Ss who did not have this experience.

The first hypothesis asserted that there would be a difference in the measured level of anxiety for the Ss 19

experiencing hallucinoidal visual imagery. Four measures of anxiety were used: the sensitizer-represser dimension, the IPAT second order anxiety factor, the Taylor NAS, and the Maslow S-I Inventory. The relationship of sensitizers and repressers to hallucinoidal visual imagery was assessed by a chi square. Sensitizers and repressers were classified into those who had experienced hallucinoidal visual imagery and those Ss who had not. This gave a two-bytwo classification. The chi square obtained was not significant (p = .26, 1 df). Therefore, on the basis of this statistic, hallucinoidal visual imagery was not found to be related to the sensitizer-reprepresser personality measure.

The IPAT second order anxiety factor was the second anxiety measure. The Ss who experienced hallucinoidal visual imagery obtained a mean score of 50.09 on this measure, while the Ss who did not experience hallucinoidal visual imagery had a mean score of 48.97. A t test of the independent means was not significant (t = 0.29, df = 54, p = .77). The Taylor MAS scores for the Ss who experienced hallucinoidal visual imagery and the Ss who did not were 17.45 and 19.44, respectively. A t test of the difference between these two independent means was not significant (t .68, = =68, df 54, p = .50). The Maslow S-I Inventory also did not reveal a significant difference. The Ss who produced hallucinoidal visual imagery obtained a mean score of 22.92, while the Ss who did not experience hallucinoidal visual imagery had a mean score of 18.21. The





23


t test indicated that the difference between these two means was not significant (t = 1.03, df = 40, p = .31).

Therefore, the weight of the foregoing evidence does not support the first hypothesis. Hallucinoidal visual imagery was not found to be related to these four measures of anxiety.
The second hypothesis questioned the relation between certain personality measures and the hallucinoidal visual imagery response. Eighteen measures from the IPAT and ten measures from the MMPI were used. The t test did not support a significant difference between the means of the Ss who gave hallucinoidal visual imagery and those Ss who did not for any of these measures. Table 1 presents the means, obtained t values, the degrees of freedom, and the level of significance for these personality measures. The MMPI Hysteria scale was one personality measure which approached an acceptable level of confidence (t = 1.96, df =5, = .06). Also, the mean scores on the IPAT factor A (schizothymia vs cyclothymia) suggested a differentiating trend (t a 1.89, df = 54, P = .07). Aside from these two questionable findings, the data support the second hypothesis in finding no significant differences between the hallucinoidal visual imagery group and the group reporting no such experiences.
The third hypothesis was concerned with the relation between two measures of ego strength and hallucinoidal visual imagery. The IPAT factor C yielded a mean score

of 17.45 for the Ss who experienced hallucinoidal visual imagery and 17.76 for the Ss who did not report hallucinoidal visual imagery. The t test of the difference between these means indicated tha that the difference was not significant (t 0.33, df = 54, p .74). The second measure of ego strength was the Barron Ego Strength scale. A mean score of 42.59 was obtained by the Ss who experienced hallucinoidal visual imagery, while the Ss not experiencing hallucinoidal visual imagery obtained 42.26. The t test of the difference between these means did not reach significance (t = 0.20, df = 54, p = .84). Therefore, the evidence presented did not support the third hypothesis.

The fourth hypothesis predicted that scores on the
IHA questionnaire would have a positive relationship with hallucinoidal visual imagery. The group of Ss reporting hallucinoidal visual imagery obtained a mean score of

5.27, while the Ss who did not report hallucinoidal visual imagery had a mean score of 5.72. The t test of the difference between these two means was not significant (t = 1.03, df 54, p .59).

The IHA questionnaire had one question referring to the hypnagogic phenomenon. Twenty-seven per cent of the Ss answered this question affirmatively. It was noted that 41 per cent of the group reporting hallucinoidal visual imagery answered this question in a positive direction; whereas, only 18 per cent of the group not reporting





25

hallucinoidal visual imagery answered in the same way. This finding is in agreement with the Freedman and Greenblatt (1960b) study in which they reported a significant relationship between a history of hypnagogie imagery and reported imagery in sensory deprivation.
The fifth hypothesis sought a relationship between performance scores on the EFT and hallucinoidal visual imagery. The group reporting hallucinoidal visual imagery obtained a mean score of 12.91 minutes, while the other group had a mean score of 15.84 minutes. The t test for the significance of the difference between these two means was not significant (t = 1.57, df 54, p = .13).
The rating scales (Appendix IV) used to evaluate behavior during sensory deprivation proved to be of little value. The sensory deprivation experiment did not produce remarkable differences among the Ss. The post-experimental interview (Appendix III) yielded some information about the desire of the Ss to terminate the sensory deprivation. Of the 42 S8 specifically queried, 12 Ss admitted that they had at least considered terminating; five of these Ss were in the group that reported hallueinoidal visual imagery. Also, 11 of the Ss who had considered terminating were sensitizers and only one was a represser.
















DISCUSSION


The relationship between reported hallucinoidal visual imagery and certain personality measures was studied. An experimental method similar to the Hochberg, Triebel, and Seaman study (1951) involved the exposure of 56 Ss to chromatic, homogeneous visual stimulation for a period of ten minutes. This brief sensory deprivation procedure was sufficient to elicit hallucinoidal visual imagery from 22 of the 56 student nurses used as So.

No significant relationships between hallucinoidal
visual imagery and these personality measures were observed. The absence of a significant relationship is in keeping with some other reports in the literature. It may be interesting, however, to use these and several other personality measures with a more extreme scoring group. The range of scores obtained from this group of student nurses was not extreme.

There were several limitations inherent in the present study. In the verbal reporting sensitizers might have tended to exaggerate their emotional difficulties, while the repressers might have tended to minimize theirs. Therefore, it is possible that some Ss did not give accurate 26





27

reports of the hallucinoidal visual imagery. The purpose of the instructions was to obviate, or minimize, such tendencies and the Ss were given several opportunities to complete their report, but the effectiveness of these measures are uncertain.

The problem of defining just what constitutes hallucinoidal visual imagery is a thorny one. Goldberger (1961) reported that a majority of his Ss reported ideoretinal phenomena, about one-half of the Ss reported that the field turned gray (adaptation), and five Ss responded with imagery. Probably some ideoretinal phenomena were mistakenly labeled as hallucinoidal visual imagery in the present study. The problem of whether or not a perception was hallucinatory or not in the classical sense has not been adequately settled in sensory deprivation studies. "Out-thereness" and "belief" have been used as indicators of hallucinatory behavior, although many researchers apparently rely on the S's verbal report. The hallucinatory qualities were assumed in the present study, as being evidenced by the fact that a report of hallucinoidal visual imagery was given without suggestion by the experimenter.
In reviewing the literature on sensory deprivation, it is evident that most of the Ss were male. Less than 30 per cent of the So were female. There was a need, therefore, for more studies with female So. Failure to find agreement with previous studies on several of the





28


personality measures, for example the Embedded Figures Test and the ego strength scales, may be due to sex differences. However, the results of the majority of the findings were in agreement with the literature.













CHAPTER V





A study was undertaken to investigate the relationship between hallucinoidal visual imagery and certain personality measures. Sensory deprivation was achieved by exposing each S to chromatic, homogeneous visual stimulation for a period of ten minutes. Of the 56 student nurse Ss, 22 reported hallucinoidal visual imagery.

No relationships were found between hallucinoidal visual imagery and the various measures used which included the VMPI, IPAT 16 P.F. Test, two measures of ego strength the Embedded Figures Test, four measures of anxiety, and the Index of Hallucinatory experience.

It's like a round center of a rose with a brownish-gray
all around it. (6 minutes)

ready to go to sleep. Sort of a sign I 'm getting ready
to drop off. (7 minutes)

like that. (9 minutes)

M~y eyes feel like they are running together. I feel
like I'm getting cross-eyed. (4 minutes)
It looks like it's still red, but not as bright as
it was at first. Looks like little lines go across the
red like sea-weed. As it goes back and forth it tends
to go in a circular motion (eyelashes). It's about the same but my head feels like it is getting
real heavy. Especially my eyes. (7 minutes)
The redness is sort of fading out. It's sort of
a lavender color coming in. Around the edges it is
dark with tinges of pink. I see the wavy lines once

fast. I don't feel any different, Just resting. (4

seems as if a light in the background. (7 minutes)
Completely black now. I still feel Just the same, real
relaxed. (8 minutes)
This eye is dark, the other has a light shining. Not red.
Just like a light shining. (9 minutes)

Still red. I feel like I've got my eyes shut. (1 minute) It's lighter red now. A pink. About the same. Sort of a reddish-orange or light orange.
Can't tell. I'm getting used to it. Feel fine. (2 minutea)
Still looks about the same to me. Still a reddish-orange.
(3 minutes)
It's getting to be darker red, I think. (4 minutes) Same color. It's almost white, it feels like. (5 minutes) It's sort of pink looks like it's going into a white

CHAPTER I INTRODUCTION Studies of sensory deprivation have been a fruitful method of studying a S_*s response to the relative absence of the usual environmental stimuli. One of the significant findings is the relatively high percentage of normal Ss who experience various hallucinations when placed in isolation. This hallucinatory activity has been studied largely in terms of the experimental conditions most likely to elicit this aberrant behavior. The personality factors of the Sa responding with hallucinatory activity has been less thoroughly studied. Although many studies have utilised personality measures, there does not emerge any consistent, significant relationship which would predict the tendency to respond with hallucinations. The Zuckerman, Albright, Marks, and Miller study (1961) concluded, "Personality correlations with response to isolation were few and no strong support was obtained for the hypothesis concerning these relations" (p. 16). They suggested further research using normal Ss who were at the extremes of some personality measure. An important personality measure which has not been systematically studied In sensory deprivation is anxiety. 1

PAGE 6

Anxiety plays a central role In human behavior. Hallucinatory activity could well be an expression of anxiety. Penlchel (19^5) points out that the anxiety hysteric frequently experiences hallucinations, in addition to other anxiety reducing symptoms. Sensory Deprivation and Perception Hoehberg, Triebel, and Seaman (1951) reported unusual behavior in 11 Ss while attempting to explore the parameters of color adaptation. A similar observation was made by Cohen {i960) who reported his Ss suffered from perceptual disturbances, dizziness, and depersonalization. Heron, Doane, and Scott (1956) had three Ss in sensory deprivation for six days, and then tested them for perceptual disturbances. They found evidence of gross disturbances. Preedman and Greenblatt (1960a) subjected 30 Ss to an eight-hour period of sensory deprivation, and then administered these Ss some standard perceptual tests. They, however, were unable to find any significant distortions. Doane, Mahatoo, Heron, and Scott (1959) using up to four days in isolation found that visual perceptions were more grossly disturbed in 13 Ss restricted to a cubicle, than were found in four Ss who were ambulatory. This was further supported by Courtney, Davis, and Solomon (1961) itfho varied the amount of movement that their 18 Ss could experience while undergoing four hours of sensory deprivation The problem of perceptual disturbance resulting from

PAGE 7

sensory deprivation has not been completely settled. The amount of time spent in isolation and the amount of physical restriction appear to be relevant variables. However, both of these variables could be associated with intensifying the S's anxiety. Profound anxiety could well interfere with performance. The function of anxiety was further suggested by the fact that the perceptual disturbances quickly abate, leaving no known permanent effects. Sensory Deprivation and Personali ty Specific research on the relation of personality to response elicited in sensory deprivation have not yet yielded conclusive results. Azima and Cramer (1956) and Azima and CramerAsima (1957) have done several sensory deprivation studies with a total of 19 mentally disturbed Ss. They found that the obsessive-compulsive neurotics became psychotic under such conditions. Azima and Cramer reported the following pattern that their Ss seemed to follow during sensory deprivation: frustration leading to aggression, followed by an introversion of the aggression causing a split in the ego, and finally depersonalization, Goldberger and Holt (1958, 196l) and Holt and Goldberger {1959} have studied the response to sensory deprivation with selected personality correlates in 30 Ss They found that the Barron Ego Strength Scale (Es) from the Minnesota Multiphasic Personality Inventory (MMPI) correlated .71 with the adaptive reactions to sensory deprivation. There were also findings in relation to

PAGE 8

passivity and adaptation. Male Ss who scored high on feminine identification were able to adapt; whereas, male actors (some with a homosexual orientation) with low ego strength were nonadaptive Wexler, Mendelson, Lelderman, and Solomon (1958) using a tank type respirator for a 36-hour period with 17 Ss, found one significant personality variable related sensory deprivation. This was the Need Exhibition scale from the Edwards Personal Preference Schedule. This was negatively correlated with the length of time the Ss remained in sensory deprivation. Bressler, Silverman, Cohen, and Shmavonian (1959) created an artificial traumatic neurosis in their study of sensory deprivation. They simply abducted three student £s, placing each S in sensory deprivation for two hours with no instructions. They found that this was extremely upsetting to these Ss, even to the point of precipitating some rather serious emotional upsets. Smith and Lewty (1959) found that nine female Ss could endure sensory deprivation for significantly longer periods than could the 11 males in their study. They further reported that the calm, placid person of average or slightly below average Intelligence was the best £. They reported a behavioral sequence? (l) sleep, with those Ss who did sleep being better able to tolerate the conditions j (2) a period of restlessness and agitation; (3) the development of disorders in thinking; and (4) the last stage, panic. Isolation was then terminated

PAGE 9

Freedman and Greenblatt (1960b) studied 30 Ss using an eight-hour period of sensory deprivation under three conditions; non patterned vision and auditory input, blacked out vision and auditory input, and social isolation. They found that the Ss who normally experience hypnagogic imagery and tended to have a rich visual experience were more apt to report hallucinations, Cambareri (1959) investigated the effects of sensory deprivation through water immersion with the suggestible and nonsuggestible. Using 20 graduate students in psychology as Ss, he found that the suggestible Ss were able to tolerate isolation longer. The suggestible Ss were also able to produce more regressive phenomena, were less threatened by it, and were less defensive about the experimental situation. Grunebaum, Freedman, and Greenblatt (i960) investigated some gross clinical types. They reported that the three schizoid Ss found the experience undisturbing, experienced little imagery, and In general showed a lack of involvement in the whole proceedings. Two borderline state Ss reacted differently. The first £, who admitted to enjoying both homosexual and heterosexual practices, became panic stricken when faced with his own imagery, while the other S, who was heterosexual, passive, and withdrawn, was able to tolerate very threatening fantasies and imagery. Two psychopathic Ss forced the experimenter to terminate the experiment by taking off the equipment, telling the

PAGE 10

experimenter that they did not think it made any difference. The conclusion of this study was that the Ss react in their characteristic manner in an ambiguous situation. Davis, McCourt, and Solomon (i960),, studying the effects of visual stimulation on hallucinations during sensory deprivation, kept ten Ss in a tank type respirator for ten and one-half hours. The found a significant relationship between the Ss who tended to respond with visual hallucinations and their performance of a "hidden figures test." They found that the better the performance, the more likely the S_ would experience visual hallucinations Although a summary of personality and sensory deprivation was complicated in view of the diverse techniques and the various Ss used, anxiety appeared to play a strong role in many studies. The Ss found to experience difficulty in sensory deprivation were: the obsessive -compulsive neurotics, Ss needing to be the center of attention, those with low ego strength, the nonsuggestible, and certain borderline states. On the other hand, there did appear to be less anxiety in those Ss who were able to adapt or endure isolation for longer periods: the Ss with high ego strength, those who were passive and calm, and the suggestible. The percentage of Ss reporting visual hallucinations in sensory deprivation had not received a systematic analysis. It was difficult to ascertain the proportion of Ss who made such a response because of the diversity of approaches

PAGE 11

to sensory deprivation, the temporal differences, and inadequate information on this point. The percentage of Ss responding 'With visual hallucinations varied between 5 per cent (Smith and Lewty, 1959) and 100 per cent (Lilly, 1956$ Shurley, i960). Talcing an average of five studies in which the Ss were submitted to unaptterned vision for periods of four to eight hours, approximately 37 per cent of these Ss experienced visual hallucinations. Although visual hallucinations were reported by a high percentage of Ss, only three studies reported significant variables that would identify these Ss. These studies indicated that good performance on the Embedded Figures Test (EFT), the more suggestible Ss, and those who have visual hallucinations in sensory deprivation. This group also appeared to have a high level of anxiety. It seemed that visual hallucinations and anxiety were related. If this was so, then one could expect a group of £s chosen for having a high level of anxiety to respond to sensory deprivation with visual hallucinations. Hypotheses On the basis of the foregoing review of the studies on sensory deprivation and personality, It was felt that the role of anxiety was sufficiently important to warrant the following hypothesis: Hypothesis 1 — That hallucinoidal visual imagery will be elicited from the more anxious Ss, and not from the less anxious Ss

PAGE 12

s In order to explore further the area of personality relationships and specify them more completely as they have been studied under sensory deprivation, major measures of the IPAT 16 P.F. Test and the clinical scales of the MMPI will be obtained on the Ss. The following hypothesis is presented: Hypothesis 2 --That Ss who have hallucinoidal visual imagery will not show differences on these personality measures The Goldberger and Holt studies (1958, 1959, and 1961) have indicated that there was a positive relationship for ego strength and the S's ability to adapt to sensory deprivation. They obtained a rho correlation of 0.44 between the MMPI es scores and visual imagery. An attempt will be made to expand these findings. The IPAT ego strength factor will be used in addition to the MMPI Es. The following hypothesis is offered: Hypothesis 3 — That Ss with higher ego strength scores will have more hallucinoidal visual imagery than will the Ss with lower measures of ego strength. The freedman and Greenblatt study {1960b} reported that Ss who had experienced hypnogogic imagery and had rich visual experiences had a higher incidence of visual hallucinations in sensory deprivation. In the light of these findings a 20item questionnaire was constructed. The purpose of this Index of Hallucinatory Activity (H-IA) questionnaire {Appendix II) was to obtain a hallucinatory

PAGE 13

behavior differential on the Ss. The following hypothesis is to fee tested: Hyp othesis 4 — That those Ss with higher scores on the Index of Hallucinatory Activity questionnaire will respond with nacre hallucinoidal visual imagery than will the Ss with lower scores „ Visual hallucinations were positively correlated with the performance on a "hidden figures test" in the Pavis, McCourt, and Solomon study (i960). These findings will be further investigated. The following hypothesis is offered: H yp o the s is 5 — That an analytical visual perception, as measured by an embedded figures test, will show a positive relationship with the production of hallucinoidal visual imagery.

PAGE 14

CHAPTER II METHOD The present study utilized a brief sensory deprivation procedure similar to the experimental procedure of Hochberg, Trie be 1, and Seaman (1951) to seek differences in those Ss who responded to chromatie, homogeneous visual stimulation ( Ganzfeld ) with the response of halluoinoidal visual imagery. Anxiety was the main personality difference in the two groups of Ss A ten-minute exposure to the chromatic Ganzfeld constituted the sensory deprivation condition. The main personality measure under study was the sensltizer-represser dimension. Welsh (1956) developed MM? I scales for identifying these two groups, the A scale for sensitizers and the R scale for repressers. The sensitizers had a high loading on the MMPI scales of Psyehasthenia and Schizophrenia-, and low scores on the K scale. They tended to be dysthymic (tending towards depression) and dysphoric (generalised anxiety, restlessness, and depression of spirits) Welsh described this factor as anxiety or being generally emotionally upset. On the other hand, the repressers were described as those Ss who characteristically rely on the defense mechanism of repression and denial. They showed a 10

PAGE 15

11 moderate loading on the MMPI scales of Hypochondriasis, Depression, and Hysteria; while they showed a moderately negative loading on the Hypomania scale. Welsh reported that the main factor here was a reliance on the defense mechanism of repression. The research of Holzsaan and Klein (1956) with what they called sharpening and leveling and the research of Wltkin, Lewis, Machover, Meissner, and Wapner (1954) on the field analytical and the field dependent characteristics suggested a similarity to the sensitizer-represser work of Welsh. The sensitizers had much in common with the sharpeners and the field analytical? alert to changes in the environment, resistant to "ground" influences, and more active. The repressers had some of the traits of the levelers and the fie Id -dependent : passive, dependent, exaggerated need for nurture and succor. The use of the term visual imagery in the several studies indicated some confusion. Most researchers preferred to use the term hallucination. Some* like Holt, preferred the term imagery or visual imagery, possibly feeling that the terra hallucination should be reserved for the more disordered mental conditions. In the present study, the term hallucinoidal visual imagery was used to label the visual sensations perceived by the Ss in response to the chromatic Ganzf eld Subj ects The Ss utilized in this study of sensory deprivation

12 were 56 female student nurses in psychiatric training at the Milled geville State Hospital, Milledgeville, Georgia. Their ages ranged from 19 to 20 years. They were at the end of their second year, or the beginning of the third year of their training, In a three-year nursing school program. Their home hospitals were located in the state of Georgia. The Ss were selected each quarter during a one-year period from a total of 299 students. They were selected on the basis on their scores on the A scale and the R scale of the MMPI. Welsh (1956) developed the scales for making this selection, and his female sample was used in. determining the cutoff scores for the Sjs utilized in this study. Ss t*iere selected whose scores were in the fourth quartile of one measure, while also being in the first quartile on the other measure. There were 28 sensitizers and 28 repressers • The Ss were encouraged to participate in the study by the promise of a brief personality evaluation based on the test battery administered to them. It was noted that the Ss were highly motivated, as no one failed to appear after being selected, no one missed an appointment, and no one was even late for an appointment. Apparently, the £s were able to keep the nature of the study secret until a group had completed the sensory deprivation procedure, as only two Ss admitted to any real foreknowledge of the ex> perimen ta 1 proced ure

PAGE 17

1^J Apparatus The Ss were asked to lie on a cot with eye cups placed over each eye. The eye cops were made from halved ping pong Mils and were held in place by means of a strip of clear, plastic wrapping material. A red light before a 10inch .aluminum parabolic reflector provided illumination measured at approximately 5^~ foot candles by a Macbeth illuiainometer. The source was placed approximately 12 inches immediately above the face of the supine §U The source was placed In position only after the S_ had the eye cups in place. Figure 1 is a posed photograph of the experimental room and apparatus. The room used for the study was located in a dormitory building. It was window less, quiet, and completely darkened during the experimental procedure. A tape recorder, placed within three feet of the head of the S, recorded verbalizations of the £ while she was participating in the experiment Procedure The Ss where chosen for the study within two weeks after their arrival at the Milledgevllle State Hospital. They were administered the MMPI. In order to maintain a degree of anonymity, each MMPI answer sheet was assigned a number to which the student nurse was asked to add her mother's maiden name. Within the next week, the Ss were selected for the study and were administered the remainder of the test battery. This included the following: the

PAGE 18

Ik IPAT 16 P.F. Questionnaire, 1956 edition, form A; the Index of Hallucinatory Activity (IHA) questionnaire (Appendix II); and Maslow's Security-Insecurity Inventory (S-I). The Witkin (1950) Embedded Figures Test (EFT), short form (Jacks on, 1956), was administered after the sensory deprivation. Specific variables from the MMPI and the IPAT were investigated. The scales from the MMPI were: K, hypochondriasis (Hs), depression (D), hysteria (HyJ, psychopathic deviate (Pd), masculinity-feminity interest (Mf), paranoia (Pa), psyehasthenia (Pt), schizophrenia (Sc), hyposiania (Ma), Barron *s (1953) Ego Strength (Es), and Taylor's (1953) Manifest Anxiety (MS). The factors utilized from the IPAT were the standard 16 factors plus the second order anxiety factor and the second order introversion-extroversion factor. The scoring of the tests was standard with the following exceptions The raw scores on the IPAT were converted to the norms of the general population, nonstudent, women, 1959 for the calculation of the second order factors. The IHA was scored by totaling the number of times the £ answered a statement "Often" or "Sometimes." When the £[ was lying on the cot with the eye cups In place, the instructions were read, the red light turned on, and the overhead illumination was turned off. Except for the red light, the room was then completely dark. Instructions read to the Ss were as follows :

16 This is a study In color adaptation, I want you to report any change in, color, any unusual feelings, or anything you might see* I would like a constant report from you which will he tape recorded. I will ask you questions from time to time. Please lie as still as you can. Don't move about any more than, you must. Bow, what do you see? It was found" -necessary to ask the Ss for a report at oneminute Intervals, as there was a strong tendency for the Ss to remain silent. The questions asked were: "What color is it," "What do you see now," or "How do you feel now." Only one question was asked at each interval; and, in general, the experimenter limited his verbalisations. The instructions used were a deliberate attempt to disguise the real purpose of the study. Kandel, Myers, and Murphy (1958) have indicated that prior instructions tend to structure the Ss response. The frequency with which the questions were asked during the sensory deprivation procedure might limit the interpretation of the results. There were two factors involved, one positive and. one negative. On the positive side was the necessity of gaining an ongoing verbal report. Visual or other sensory experiences might well be minimized or distorted in a post -experimental interview. On the negative side was the fact that the experimenter's voice tended to act as a reality guide. This was anticipated, and later substantiated in the case of S 270 R 2k. Immediately after the ten-minute interval of sensory deprivation, the £ was Interviewed as to how she felt and what she had experienced. The standardised interview

PAGE 21

17 (Appendix III) was a modification of the Goldberger and Holt {1961) post -experimental interview. A rating scale (Appendix IV} was utilised to evaluate the S's behavior. The verbalisations elicited from the Ss while undergoing sensory deprivation were rated by six judges for evidence of hallucinoidal visual imagery. The judges referred to the Type of Hallucination rating scale (Appendix IV") in making their judgments. This rating scale was a modification of the scale reported by Vernon, MeGill and Schlffman (1958). Four of the six judges had to agree in their independent rating on the presence of verbalisations which indicated the probability of S experiencing hallucinoidal visual imagery. The resulting unreliability of the five categories of the types of hallucination indicated that the most feasible method of evaluation would be a two-fold classification: those Ss who experienced hallucinoidal visual imagery and those Ss who did not have this experience. An appropriate method for analysing the data obtained was to compare the mean scores on the various personality measures for the group who experienced hallucinoidal visual imagery and the group that did not have this experience. The t test for the difference between independent means was used to test the null hypothesis. A chi square was used to determine the relationship in the frequency distribution of the hallucinoidal behavior by the sensitizers and the repressers. A two -by-

18 two chi square was utilized to test the distribution of the sensitizers .and the repressers who had and had not experienced hailucinoidal visual imagery. Seven rating scales and the post-experimental interview were searched for significant relationships.

CHAPTER III RESULTS Hallueinoidal visual imagery was elicited from 22 (39$) of the Ss during a ten-minute period of color adaptation in a field of homogeneous visual stimulation ( Ganzfeld ) The presence of hallueinoidal visual imagery was established through the rating of the verbalizations of the Ss during the experimental procedure. Six judges were used for the evaluation, and agreement among four of the six Judges was the criterion for the presence of hallueinoidal visual imagery. The Ss judged by this criterion are presented in Appendix 1 (Table 2). The transcription of the verbalisations of the Ss are presented in Appendix V* It was noted in placing the Ss in the hallueinoidal visual imagery group that the Type of Hallucination rating scale (Appendix IV) was not sensitive enough to establish a quantification of the type of imagery. Therefore, the analysis of the dependent variable was limited to a dichotomy: those Ss who experienced hallueinoidal visual imagery and those £s who did not have this experience. The first hypothesis asserted that there would be a difference in the measured level of anxiety for the Ss 19

experiencing hallucinoidal visual imagery. Pour measures of anxiety were used: the sensitizer-represser dimension, the IPAT second order anxiety factor, the Taylor MAS, and the Mas low S-I Inventory. The relationship of sensitizers and repressers to hallucinoidal visual imagery was assessed by a chi square. Sensitizers and repressers were classified into those who had experienced hallucinoidal visual imagery and those Ss who had not. This gave a two-bytwo classification. The chi square obtained was not significant (£ s .26, 1 df ) Therefore, on the basis of this statistic, hallucinoidal visual imagery was not found to be related to the sensitizer-represser personality measure. The IPAT second order anxiety factor was the second anxiety measure. The Ss who experienced hallucinoidal visual imagery obtained a mean score of 50. 09 on this measure, while the Ss who did not experience hallucinoidal visual imagery had a mean score of 48.97. A t_ test of the independent means was not significant (t_ 0.29, df • $4, p .77). The Taylor MAS scores for the Ss who experienced hallucinoidal visual imagery and the Ss who did not were 17.45 and 19.44, respectively. A t test of the difference between these two independent means was not significant (t 0.68, df 54, p .50). The Maslow S-I Inventory also did not reveal a significant difference. The Ss who produced hallucinoidal visual imagery obtained a mean score of 22.92, while the Ss who did not experience hallucinoidal visual imagery had a mean score of 18.21, The

PAGE 27

23 lb test indicated that the difference between these two means was not significant (t 1.03, df 40, p_ .31). Therefore, the weight of the foregoing evidence does not support the first hypothesis. Hallueinoidal visual imagery was not found to be related to these four measures of anxiety. The second hypothesis questioned the relation between certain personality measures and the hallueinoidal visual imagery response. Eighteen measures from the IPAT and ten measures from the MMPI were used. The t test did not support a significant difference between the means of the Ss who gave hallueinoidal visual imagery and those Ss who did not for any of these measures. Table 1 presents the means, obtained j| values, the degrees of freedom, and the level of significance for these personality measures. The MMPI Hysteria scale was one personality measure which approached an acceptable level of confidence (£ 1.96, df = 5k, £ = .06). Also, the mean scores on the IPAT factor A (schizothymla vs cyclothymia) suggested a differentiating trend (t 1.89, df 5k, p • .0?). Aside from these two questionable findings, the data support the second hypothesis in finding no significant differences between the hallueinoidal visual imagery group and the group reporting no such experiences. The third hypothesis was concerned with the relation between two measures of ego strength and hallueinoidal visual imagery. The IPAT factor C yielded a mean score

PAGE 28

24 of 1?.#5 for the Ss who experienced hallucinoidal visual Imagery and 17. 76 for the Ss who did not report hallucinoidal visual imagery. The t test of the difference between these means Indicated that the difference was not significant (t O.33, df 5%, p • .7*). The second measure of ego strength was the Barron Ego Strength scale. A mean score of 42.59 was obtained by the Ss who experienced hallucinoidal visual Imagery, while the Ss not experiencing hallucinoidal visual imagery obtained 42.26. The t test of the difference between these means did not reach significance (t • 0.20, df 54, £ m .84). Therefore, the evidence presented did not support the third hypothesis. The fourth hypothesis predicted that scores on the IHA questionnaire would have a positive relationship with hallucinoidal visual imagery. The group of £s reporting hallucinoidal visual imagery obtained a mean score of 5.27, while the Ss who did not report hallucinoidal visual imagery had a mean score of 5.72. The t test of the difference between these two means was not significant (t I.03, df 54, p .59). The IHA questionnaire had one question referring to the hypnagogic phenomenon. Twenty-seven per cent of the Ss answered this question affirmatively. It was noted that 4l per cent of the group reporting hallucinoidal visual imagery answered this question in a positive direction! whereas, only 1-8 per cent of the group not reporting

PAGE 29

hallucinoidal visual imagery answered in the same way. This finding is in. agreement with the Freedman and Greenblatt (l9'60b) study in which they reported a significant relationship between a history of hypnagogic imagery and reported imagery in sensory deprivation. The fifth hypothesis sought a relationship between performance scores on 'the EFT and hallucinoidal visual imagery. The group reporting hallucinoidal visual imagery obtained a mean score of 12.91 minutes, while the other group had a mean score of 15.8^ minutes. The Jb test for the significance of the difference between these two means was not significant (Jb 1.57* df • 5^, p X3). The rating scales (Appendix IV) used to evaluate behavior during sensory deprivation proved to be of little value. The sensory deprivation experiment did not produce remarkable differences among the Ss. The post-experimental interview (Appendix III) yielded some information about the desire of the Ss to terminate the sensory deprivation. Of the ^2 Ss specifically queried, 12 Ss admitted that they had at least considered terminating^ five of these Ss were in the group that reported hallucinoidal visual imagery. Also, 11 of the Ss who had considered terminating were sensitizers and only one was a represser.

PAGE 30

CHAPTER IV DISCUSSION The relationship between reported hallucinoidal visual imagery and certain personality measures was studied. An experimental method similar to the Hoehberg, Triebel, and Seaman study (1951) involved the exposure of 56 Ss to chromatic, homogeneous visual stimulation for a period of ten minutes. This brief sensory deprivation procedure was sufficient to elicit hallucinoidal visual imagery from 22 of the 56 student nurses used as Ss No significant relationships between hallucinoidal visual imagery and these personality measures were observed. The absence of a significant relationship is in keeping with some other reports in the literature. It may be interesting, however, to use these and several other personality measures with a more extreme scoring group. The range of scores obtained from this group of student nurses was not extreme There were several limitations inherent in the present study. In the verbal reporting sensitizers might have tended to exaggerate their emotional difficulties, while the repressers might have tended to minimize theirs. Therefore, it is possible that som<= Ss did not give accurate 26

PAGE 31

2? reports of the hallucinoidal visual imagery. The purpose of the instructions was to obviate, or minimize, such tendencies and the £s were given several opportunitiesto complete their report, but the effectiveness of these measures are uncertain.. The problem of defining just what constitutes hallucinoidal visual imagery is a thorny one. Goldberger (1961} reported that a majority of his Ss reported ideoretinal phenomena, about one-half of the Ss reported that the field turned gray (adaptation), and five Ss responded with imagery. Probably some ideoretinal phenomena were mistakenly labeled as hallucinoidal visual imagery in the present study. The problem of whether or not a perception was hallucinatory or* not in the classical sense has not been adequately settled In sensory deprivation studies. !, Gut-thereness" and "belief" have been used as Indicators of hallucinatory behavior, although many researchers apparently rely on the £ f s verbal report. The hallucinatory qualities were assumed in the present study, as being evidenced by the fact that a report of hallucinoidal visual imagery xms given without suggestion by the experimenter. In. reviewing the literature on sensory deprivation, it is evident that most of the Ss were male. Less than 30 per cent of the Ss were female. There was a need, therefore, for more studies with female Ss. Failure to find agreement with previous studies on several of the

PAGE 32

28 personality measures, for example the Embedded Figures •Test and the ego strength scales, my be due to sex differences. However, the results of the majority of the findings were in agreement with the literature.

CHAPTER V SUMMARY A study was undertaken to investigate the relationship between hallucinoidal visual imagery and certain personality measures* Sensory deprivation was achieved by exposing each S_ to chromatic, homogeneous visual stimulation for a period of ten minutes. Of the 56 student nurse Ss, 22 reported hallucinoidal visual imagery. No relationships were found between hallucinoidal visual imagery a&d the various measures used whieh included the MtfXj IPAT 16 P.P. Test, two measures of ego strength, the Embedded Figures Test, four measures of anxiety* and the Index of Hallucinatory experience 29
